Asymmetric Structure‐Driven Functional Synergy: A Multistimuli‐Activated Janus Nanomotor for Self‐Amplifying NO Cascade Therapy

open access: yesAdvanced Science, EarlyView.
The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.

Multienzyme complexes of eukaryotic aminoacyl-tRNA synthetases

open access: yesBioscience Reports, 1983
The high-molecular-mass aminoacyl-tRNA synthetase complexes in higher eukaryotes are discrete non-artifactual multienzyme complexes of similar composition which can be purified from different tissues of different species by different techniques. These high-Mr complexes are composed of synthetases in simple stoichiometric ratios.

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...
